The plants can tolerate light frost and thrive in sun or semi-shade. Plant in a free-draining soil and water only when the soil is almost dry. They can be propagated from tip cuttings, but are frequently grown as half-hardy annuals. They are suitable for container gardening and hanging baskets and will attract hummingbirds.
Once potted, the rooting media need to be kept moist and the cuttings need to be misted regularly. The cuttings should develop an adequate root system for transplantation in about three months. It has been determined that rooting hormones containing higher levels of IBA increase the percentage of cuttings that develop viable roots in Carolina ...
A piece of the stem or root of the source plant is placed in a suitable medium such as moist soil. If the conditions are suitable, the plant piece will begin to grow as a new plant independent of the parent, a process known as striking. A stem cutting produces new roots, and a root cutting produces new stems. Some plants can be grown from leaf ...
Plant propagation is the process by which new plants grow from various sources, including seeds, cuttings, and other plant parts. Plant propagation can refer to both man-made and natural processes. Propagation typically occurs as a step in the overall cycle of plant growth.
Ruellia is a genus of flowering plants commonly known as ruellias or wild petunias. [3] They are not closely related to petunias (Petunia) although both genera belong to the same euasterid clade. The genus was named in honor of Jean Ruelle (1474–1537), herbalist and physician to Francis I of France and translator of several works of ...
Ruellia simplex is an evergreen perennial growing 3 ft (0.91 m) tall, forming colonies of stalks with lance-shaped leaves that are 6 to 12 in (15 to 30 cm) long and .5 to .75 in (1.3 to 1.9 cm) wide.
Root cuttings (pieces of root cut off and induced to grow a new trunk) are also not used to propagate fruit trees, although this method is successful with some herbaceous plants. A refinement on rooting is layering. This is rooting a piece of a wood that is still attached to its parent and continues to receive nourishment from it.
Petunias are generally insect pollinated, with the exception of P. exserta, which is a rare, red-flowered, hummingbird-pollinated species. Most petunias are diploid with 14 chromosomes and are interfertile with other petunia species, [ 9 ] [ 10 ] as well as with Calibrachoa .
